Application filed April 22,1911. SerialNo. 622,683.

T all whomit may concern I Be it known that I, Tirnononn T. KRYSH- TOFOVIGH, a. subject of the Emperor of Russia, and a resident of St. Louis, in the State of Missouri, have invented anew and Improved Transmission of Electric'Power,

of which the following is a full, clear, and exact description.

My invention is an improvement in Lransmission for electric power, and has for its object the provision of a convenient simple means for transmitting an electric current to aerial vehicles.

In the drawings is shown a view of the device.

In the present embodiment of the invention, the vehicle .1 receives its current through a cable Q'irom a plurality of conducting wires 3 and 4' supported by poles Each pole 5 is provided at its upper end with a cap 6, having a pair of oppositely arranged diverging arms 7 and 8. The arms dia grammatic 7 of the poles support thewire 3 and the arms 8 support the wire 4.

As shown, the wires are supported in spaced relation and the poles 5 may be of any desired or suitable length. The wires are supplied with current from any suitable form of generating device indicated by the reference character 9 and connected to the wires 3 and 4 by conductors 10 and 11 respectively.

In the drawings thc'wire 3 is the positive wire and the wire 4 is the negative. The cable 2 is composed of two conductors 12 and 13 which diverge adjacent to the trolley or carriage to be described. The said trolley or carriage consists of a pair of spaced sub-' stantially parallel bars 15 and 16 of conducting material, each of which is provided at each end with a downwardly and outwardly extending arm or extension 14. The

bars are connected and held in spaced reanaterial. Each of the angular arms 14 is' lation by cross bars 17, each of which has interposed in. its length and at approximately its center a section 18 of insulating provided at its lower end with an integral cross. head or bar 19 inclined with to the bars 15 and 16 and-provided at each' roller 22 for engagin respect end with a'journal' pin 20. A wheel or disk 21 is journaled on each of the pins 20 and each wheel is provided at each end with a the-adjacent wire 3 or 4t as the case may.

that the bars or heads 19 atthe adjacent ends of the bars 15 and 16 are inclined in the sonic direction and in the opposite direction-to the bars at'the other end. The angle of inclination is such- .that the roller 22 at the outer end of the bar 19 is'below the wire 15'or 16 while the roller at the inner end of the ba'r'is above the wire. The outermost rollers ofthe trolley or carriage are below the wires'loand" 16 while the innermost rollers are above the wires. The wheels and rollers-are 'of con-' ducting material and the respective sides of thetrolley are insulated from each other by the sections 18. The carriage is intactcomposed of two connected sections Insulated from each other. The arrangement of the rollersprevent the carriage being drawn upwardly or downwardly by tlievehicle, and the wheels 21 prevent any lateral niovement of the carriage. As shown the wire'12 of the cable is connected to the bar '15 while the wire 13 is connected to the bar'16. The carriage is free to travel on the wires 3 and 4. as indicated by thearrow and travels with the yehicle. The bars or cross heads19 are outside of the wires and it'will be noticed I that each arm ,7 and 8 is provided with a longitudinal portion 24' adjacentto the wire so thatthe arm will not interfere with the may travel-freely with the vehicle but cannot leave the conducting wires and the current passes from wire 3 to and "through bar 15 and wire 12 to the motor of "the vehicle. and returns by way of wire 13, bar 16 and wire 4 to the generator. The upper end of the cable is preferably wound on a spring reel 25 which is journaled in brackets 26 on the vehicle so that there can be no dan er of straining any of the parts by sudden changes of position on the part of the vehicle.
